Transmission
How they work:
What can happen:
A
TORQUE CONVERTER
? A hydraulic coupling that transfers engine power to the transmission
? Allows the engine to run with the vehicle stopped, by permitting a controlled amount of slip. Provides the engage/disengage function from the drive wheels at red lights
? A lockup clutch physically locks the engine output to the transmission at steady cruising speeds to eliminate slip and increase efficiency
? A seal between the torque converter and the transmission can leak fluid
? The torque converter can fill with debris from component wear and contaminate fresh fluid or a replacement transmission
? Internal components can break or bend ? The lockup clutches can slip or stop working
entirely ? The seam weld can leak
B
FLUID AND FILTER
? Fluid is the "lifeblood" of the transmission ? Keeps components cool ? Lubricates the bearings, bushings and gears ? Prevents rust ? Optimizes driving "feel" (clutch friction) ? An internal filter cleans the fluid ? Fluid/filter require periodic changes ? see
Owner Guide maintenance schedule
? Fluid can overheat (burn) and reduce the life of the transmission
? Unchanged, burned fluid eventually results in transmission failure
? Filter can eventually clog with debris (metal shavings/friction material) caused by wear
? A clogged filter can prevent fluid flow, resulting in failure
C
GEARS
? Planetary gearsets offer multiple speed ratios ? Bushings or bearings can fail
in a compact package
? Debris can damage gear teeth
? Clutches hold specific gearset components for
various gear ranges
D
OIL PUMP
? The oil pump pressurizes fluid to: ? Activate clutches ? Provide lubrication ? Move it through the transmission cooler
? The pump can fail due to wear or leakage ? Causes low or no fluid pressure ? Clutches can slip and fail
? Bushings, bearings and gears lose lubrication, causing wear or failure
? Low pressure reduces or stops fluid flow through the transmission cooler ? Transmission overheats as a result
E
CLUTCHES
? Clutch pistons are actuated by fluid pressure ? This applies the clutch to engage the friction material
? The friction materials can wear out and lose their grip, resulting in transmission slip
? Clutch piston seals can wear or fail, resulting in friction material slip and wear
F
MAIN CONTROL / TRANSMISSION CONTROL UNIT
? The Main Control and Transmission Control Unit are the combined brains of the transmission
? They direct fluid at the proper time and pressure to the clutch pistons/clutches to provide: ? Smooth shifts ? The optimum gear selection for performance and fuel economy
? Main control valves and solenoids contaminated by debris can stick, causing erratic shifting and clutch failure
TRANSELLGUIDE01-15
HOW AN AUTOMATIC TRANSMISSION WORKS:
? A torque converter harnesses and transmits the engine's rotary motion
? A hydraulic pump moves transmission fluid to the clutches and main control
? Rotary power is transferred to internal shafts and gearing
? Gearing and clutch application determines the correct combination of speed and power output to the wheels
? Rotary motion is transmitted through the differential to the drive wheels
Possible Symptoms:
? One or more gear ranges do not work (A, B, C, D, E, F)
? The engine must be revved higher than normal to make the vehicle move (A, B, C, D, E, F)
? Vehicle driveability is jerky or erratic (A, B, D, E, F) ? A burnt odor is detected (B, E) ? Excessive noise (A, C, D)
